備註

不同于大部分類別Array , 會CreateInstance提供方法, 而不是公用的函式, 以允許晚期繫結的存取。Unlike most classes, Array provides the CreateInstance method, instead of public constructors, to allow for late bound access.

參考型別元素會初始化為nullReference-type elements are initialized to null. 實值型別元素會初始化為零。Value-type elements are initialized to zero.

這個方法是 O (n) 運算, 其中nlengthThis method is an O(n) operation, where n is length.

不同于大部分類別Array , 會CreateInstance提供方法, 而不是公用的函式, 以允許晚期繫結的存取。Unlike most classes, Array provides the CreateInstance method, instead of public constructors, to allow for late bound access.

lengths陣列中的元素數目必須等於新Array中的維度數目。The number of elements in the lengths array must equal the number of dimensions in the new Array. lengths陣列的每個元素都必須在新Array的中指定對應維度的長度。Each element of the lengths array must specify the length of the corresponding dimension in the new Array.

參考型別元素會初始化為nullReference-type elements are initialized to null. 實值型別元素會初始化為零。Value-type elements are initialized to zero.

這個方法是 O (n) 運算, 其中n是中lengths所有值的乘積。This method is an O(n) operation, where n is the product of all values in lengths.
